Introduction
The poultry sector is a critical part of the livestock industry, encompassing various production levels such as breeding farms, hatcheries, feed factories, broiler and layer farms, and processing plants. It includes different species like chicken, quail, duck, turkey, guinea fowl, and goose. The infrastructure ranges from basic hatched sheds to automated, environmentally controlled ones, featuring automatic feeders, advanced watering systems, automatic egg collection, refrigeration systems, and units for manufacturing nutraceuticals, medicines, vaccines, mechanical components, and electronic gadgets. Poultry feed manufacturing involves processing different raw materials to meet the nutritional needs of birds, drawing on expertise in animal nutrition and mechanical engineering. Since the introduction of feed mills, numerous technologies have been employed to implement diverse feed manufacturing techniques. These technologies aim to produce well-balanced, cost-effective, and high-quality feed sustainably. Over the years, various technological innovations have further enhanced the environmental, social, and economic sustainability of feed manufacturing vaccine quality control, standardization and quality control of poultry feed, eggs, and meat, HACCP (Hazard Analysis and Critical Control Point) and GMP (Good Manufacturing Practices) compliance with WTO and CODEX norms, and efforts in grading, value addition, brand promotion, and export enhancement.
Globally, by the end of this decade, poultry meat is expected to account for 41% of all protein from meat sources, according to the OECD-FAO Agricultural Outlook 2030. The Indian poultry industry stands to gain from lifestyle and dietary changes, with the share of organized commercial farms increasing due to modernization and technical improvements. Government data shows a steady rise in egg production, from 95 billion in 2017-18 to 105 billion the following year, and 114 billion in 2019-20.
Similarly, poultry meat production grew from 3.7 million metric tons (mmt) in 2017-18 to 4.1 mmt the following year, reaching 4.3 mmt in 2019-20. Projections suggest that by 2023, the country could produce 136 billion eggs and 6.2 mmt of poultry meat.
The global poultry market was valued at nearly $319.2 billion in 2019, having grown at a CAGR of 5.5% since 2015, and is expected to grow at a CAGR of 6.1% to nearly $405 billion by 2023. The market is projected to grow at a CAGR of 7.2% to nearly $465.7 billion by 2025 and at a CAGR of 6.8% to $645.7 billion by 2030.
New Trends in Poultry Farming:
The COVID-19 pandemic, declared by the WHO on March 11, 2020, severely impacted many economic sectors, including livestock production. It led to production and transportation disruptions, declining consumer demand, and volatile markets, causing financial difficulties and permanent closures of many farms. Social distancing, self-isolation, and travel restrictions reduced the workforce across sectors, leading to job losses. The need for medical supplies increased, while the need for commodities and manufactured products decreased. The food sector faced increased demand due to panic-buying and stockpiling. Labor management issues prompted innovative ideas in poultry farming. Despite the challenges, new technologies offer solutions for future success.
Emerging trends in poultry farming include:
1. Genetic solutions for preventing male chicks.
2. 3D cameras for capturing precise broiler weights.
3. MRI technology for identifying fertile eggs.
4. Smartwatches for solving labor problems in poultry processing.
5. 24/7 feedback loops for improving poultry flock outcomes.
6. Collaborative robots for further automation.
7. Improved in-line poultry chilling using kinematics.
8. Preventing antibiotic resistance using peptides.
9. Digital technologies for simplifying poultry data analysis.
10. Hyperspectral imaging for detecting poultry meat defects.
11. Machine vision for detecting broiler floor distribution.
12. CRISPR technology for transforming the poultry industry.
13. Robots for meeting processing challenges.
14. Automation for preparing case-ready poultry.
15. Digitalization for optimizing productivity planning.
16. Healthy chicks establishing adult microbiomes quickly.
Technologies disrupting future production and processing operations:
1. Remote sensing allows real-time visibility of poultry house conditions, bird performance, health, and welfare. Farmers can monitor sheds and birds via computer, with sensors providing alerts if parameters deviate from requirements.
2. Sensors streamline data collection for birds and workers, enabling precision poultry production. Smart phones can monitor real-time environmental contexts like temperature, humidity, ammonia levels, and water levels. Integrated solutions using WSN (wireless sensor network) and GPRS networks facilitate smart poultry monitoring.
3. Sensors help estimate body weights, measure flock uniformity, and solve labor issues. Wearable sensors improve worker retention and food safety.
Feed ingredients for poultry
Cereal grains and their by-products:

Additives are non-nutritive substances incorporated into animal feed to enhance feed intake, digestion, absorption, and nutrient utilization, ultimately improving the growth and production performance of livestock, including poultry. Unlike nutritional supplements, additives do not directly provide essential nutrients but instead facilitate better use of the nutrients present in the feed.
Types of Feed Additives:
1. Antibiotics:
o Purpose: Used to prevent or control bacterial infections, thus promoting healthier and more productive livestock.
o Action: Suppress pathogenic bacteria in the gut, reducing disease incidence and improving feed efficiency.
o Consideration: Due to the risk of antibiotic resistance, the use of antibiotics as feed additives is now restricted or banned in many countries.
2. Probiotics:
o Purpose: Live microorganisms that, when administered in adequate amounts, confer health benefits to the host.
o Action: Improve gut health by balancing intestinal microflora, enhancing digestion and nutrient absorption.
o Examples: Lactobacillus, Bifidobacterium, Saccharomyces.
Additional Common Feed Additives:
3. Prebiotics:

Feed additives play a crucial role in optimizing the health, growth, and productivity of poultry by enhancing the efficiency of nutrient utilization and improving overall feed quality. Their strategic use, tailored to the specific needs and conditions of the livestock, can lead to significant improvements in animal performance and well-being
Antibiotics have historically been used as feed additives in poultry and swine production to promote health, growth, and productivity by mitigating the adverse effects of pathogenic organisms present in the animal’s environment. These organisms can cause subclinical infections, consuming nutrients and producing toxins that lead to intestinal inflammation and reduced nutrient absorption. Antibiotics, when administered in small amounts over prolonged periods, can suppress these microorganisms, enhance nutrient availability, reduce toxin production, and improve the overall health and growth of the animals.
Benefits of Antibiotic Feed Additives:
1. Suppression of Pathogenic Organisms: Reduces the load of harmful microorganisms in the gastrointestinal tract.
2. Improved Nutrient Availability: By reducing microbial competition, more nutrients are available for the host animal.
3. Reduced Intestinal Inflammation: Leads to thinner intestinal mucous membranes, enhancing nutrient absorption.
4. Enhanced Growth and Production: Better health and nutrient absorption result in improved growth rates and productivity.
Commonly Used Antibiotics:
– Tetracycline
– Oxytetracycline
– Auriomycins
Benefits of Probiotics as Feed Additives:
1. Enhanced Gut Health:
o Prevention of Gut Disorders: Probiotics help in maintaining a balanced gut microflora, which can prevent digestive disorders and improve nutrient absorption.
2. Improved Growth and Production:
o Growth Promotion: By enhancing nutrient absorption and gut health, probiotics contribute to better growth rates and productivity.
3. Immune System Support:
o Immune Function: Probiotics can boost the immune system, helping animals resist infections and diseases.
4. Reduction in Pathogen Load:
o Pathogen Control: By preventing pathogen colonization and reducing pathogen load, probiotics help in maintaining overall health.
Probiotics offer a valuable alternative to antibiotics in animal feeds by promoting gut health and enhancing growth and production. Their ability to competitively exclude pathogens and produce beneficial substances makes them effective in supporting overall animal well-being..
